Nivelco Instrumentation for Chemical and Pharmaceutical Industries

  2. 2. FROM R O A D S A LT … T O SULPHURI C ACI D! Instrumentation and measuring tasks of the chemical and pharmaceutical industry are covered almost fully by the wide range of NIVELCO instruments. From simple float level switches to ultrasonic or microwave radar level transmitters, from pressure transmitters to custody transfer measurement with magnetostrictive transmitters, for all applications can be selected the most suitable NIVELCO instrument with the required operating principle. Environmental and technological measurements are supported by modern liquid analytical transmitters. Instruments are also applicable for using in hazardous environment. Field transmitters can be easily integrated to process-control systems with MultiCONT multichannel process controller or NIVISION process visualisation software. FIELD INSTRUMENTS IN MEASUREMENT SYSTEMS Level and analytical transmitters can be connected to the MultiCONT process controller, or with the help of suitable interfaces or modems, NIVELCO field instruments can provide measurement results and control signals directly to the process control system. NIVISION software provides a perfect choice for process visualization, data collection, measurement-database management and process control tasks.

  3. 3. COMPRESSOR AND COOL DOWN CONDENSER The first part of a refrigerator plant using ammonia (NH3) as coolant is the refrigerator compressor which increases the pressure and temperature of the NH3. The pressure measurement on the suction and pressure side is accomplished by NIPRESS DRC-3 pressure transmitters, the temperature measurement is completed by THERMOCONT TTJ-5 temperature transmitters. The sucking side pressure transmitter performs the power control of the compressor, while the pressure side transmitter controls the condenser. The cooling condenser turns back the NH3 into liquid phase. COOLINGCIRCULATIONPROCEDURE EVAPORATOR OF THE REFRIGERATOR PLANT LIQUID SEPARATOR MOTOR COOLING COMPRESSOR AMMONIA VAPOUR LIQUID AMMONIA CONDENSER LIQUID COLLECTOR COOLING WATER TANK DRAINS SOFT WATER AMMONIA PUMP LIQUID COLLECTING AND LIQUID-SEPARATING RECIPIENT As the ammonium level decreases in the liquid-separator tank, the necessary liquid for the process is refilled from the liquid tank. The continuous level measurement is executed by NIVOCAP CTR-2 type capacitive level transmitter. This device controls the feeding valve applying the UNICONT PMM-311 type controller. The upper and lower failsafe switching is executed by NIVOMAG MKA-210 type level switches. As high level is reached the compressor shuts off, while at low level the ammonium pump is stopped. COOLING WATER TANK The condenser cooling water tank ensuring the cooling water for the condenser. The level measurement is accomplished with EchoTREK SGA-3 ultrasonic level transmitter. The level is kept constant by the help of a UNICONT PMM-311 controller by actuating a supplementary water valve. Continuous conductance measurement is executed with an ANACONT LGK-2 type device. The conductivity of cooling water is increasing due to the evaporation in the condenser. At a predetermined value PMM-311 controller opens the emptying as well as the supplementary valve.

  4. 4. GLAXOSMITHKLINE – VACCINE FACTORY AGROKÉMIA SELLYE CO. – PESTICIDE PRODUCTION GLAXOSMITHKLINE was intended on replacing the capacitive level transmitters on the vaccine fermentors so they were searching for new instruments on the market. The fermentors play central role in the vaccine production process and considering the fact that the production system consists of one-week long cycles the primary demand was the highest possible reliability. Any measurement error or failure might result unsuccessful oneweek production cycle generating significant losses. At least ±1 % accuracy continuous level measurement of different pH and density liquids (for example high purity water, washing liquid, fermentation liquid) was a strict requirements against the level transmitters and the instrument must have linearization table for volume calculation. The fermentors are regularly sterilized with steam and decontaminated so the instruments have to bear 150 °C (302°F) medium temperature. The fermentors have vibrating motors so the instruments have to measure reliably during strong vibration along with the medium movement caused by the mixing. The other essential requirement was the easy integration to the existing automation system and the high hygienic requirements involving special demands of the pharmaceutical environment. At the end of the rod probe there should be no closing element due to cleaning considerations and all wetted parts should be made from Ra < 0.4 surface roughness 316Ti stainless steel and full PFA coating. NIVELCO’s MicroTREK HHO-412-4 type guided microwave level transmitters meet all these requirements, so GSK decided to replace the capacitive level transmitters. This special type was uniquely manufactured for the first time for this project. In this plant they change the properties of the pesticide agent by adding emulsifiers and auxiliary materials which make it soluble in water. This process – called EC formatting – enables pesticide agent to be solved in water and the final result is what we known as sprayable pesticide. The organic solvents of the plant are stored in 10 outside laying tanks equipped with NIVOTRACK MTC-522-8 type magnetostrictive level transmitters with 1mm resolution. Output signals of the transmitters are displayed in a MultiCONT PRC-24A-5 Ex multichannel process controller which transfers the measurement data to the NIVISION process visualization software. The software performs stock management and fills the calibration report after the comparison with the stored receipt. Mixing of the emulsions is done in a 10 m3 (2 641 gal) vacuum tank. The filled material is measured by load cells under the tank. The temperature is measured by THERMOCONT TBC 521-8 Ex ATEX certified temperature transmitter mounted into the bottom of the tank. The solved medium from the mixing tank is forwarded to 2 pieces of 20 m3 (5 283 gal) so called “batch” tanks to be able to provide equal quality. Level measurement of the tanks is done by EchoTREK SGF-380-8 Ex compact ultrasonic level transmitters as well temperature is measured by THERMOCONT TBC-521-8 Ex temperature transmitters. A sample from this tank is examined for quality control reasons and when the laboratory approves the quality of the semi-finished product then it is allowed to go packaged. Dosing machines fills the processed material into containers. Number of the containers passing through the filling line was counted by NIRED IRV-111-1 infrared sensors.
